EVAPORATORS FOR USE IN HEAT TRANSFER SYSTEMS, APPARATUS INCLUDING SUCH EVAPORATORS AND RELATED METHODSAn evaporator includes a liquid barrier wall made of a ceramic material, a vapor barrier wall made of a ceramic material, and a wick made of a ceramic material and being positioned between the ...
This paper presents the heat transfer characteristics of the evaporators in a double-evaporator refrigerating system with an environment-friendly refrigerant, propane (R-290). Based on the Buckingham Pi theorem, dimensionless correlations are developed to predict the heat transfer coefficients of the ...
In a flooded cooler the water or brine is circulated through the tubes, which are usually finned to provide an increment in the heat transfer rate and a decrease in the evaporator size.In a dry cooler the liquid refrigerant is contained within the tubes, and water or brine is circulated ...
Pack high heat transfer efficiency and energy savings into evaporation systems, that are lower in height and weight than conventional evaporators. Versatile, energy-efficient and economical, these evaporators generally fit into the available space in existing buildings yet maximize product quality while ...

Microchannel coils perfectly fit today’s HVAC equipment requirements, providing numerous improvements over traditional heat exchangers: 20–40% higher heat transfer performance Reduction in fan power thanks to lower air resistance Ability to operate in harsh environmental conditions thanks to exceptional res...
A new method for reducing local heat transfer data in multi-microchannel evaporators was proposed.A 3D inverse heat conduction problem was solved in this new method.Experimental data of single-phase and flow boiling with infrared temperature measurements were reduced by this method.The polynomial ...
Plate Heat Exchanger Literature Survey and New Heat Transfer and Pressure Drop Correlations for Refrigerant EvaporatorsTwo-Phase Flow Patterns, Pressure Drop, and Heat Transfer during Boiling in Minichannel Flow Passages of Compact Evaporators
Large falling film evaporators with horizontal tube bundles have been widely used in industry. In air-conditioning area, compared with the flooded evaporation, the falling film evaporation employs the advantages of the high heat transfer capability with small temperature differences and the few charge ...
